Abstract

Benzofuro[3,2-c]quinoline compounds of the general formula: wherein A represents a group of the formula of ( CH₂) or -CH₂CH(OH)CH₂-; Y represents an N,N-di-alkylamino group, an N-mono-alkylamino group or a nitrogen atom-containing aliphatic geterocyclic group; n represents 0 or 1; m represents an integer of from 1 to 3, and pharmaceutically acceptable acid addition salts thereof, possess a strong inhibitory action on bone resorption, a stimulatory effect on ossification.
Furthermore, benzofuro[3,2-c]quinoline compounds of the above general formula and pharmaceutically acceptable acid additional salts thereof possess a stimulatory effect on longitudinal bone growth, and thus useful for the prevention or treatment of osteoporosis.
